T400

T400 (400 mg/mL) is for intramuscular use only. It should not be given intravenously. Intramuscular injections should be given deep in the gluteal muscle. The suggested dosage for T400 varies depending on the age, sex, and diagnosis of the individual patient. Dosage is adjusted according to the patient's response and the appearance of adverse reactions. Some experts have advocated lower dosages initially, gradually increasing the dose with or without a decrease to maintenance levels. Other experts emphasize higher initial dosages and lower dosages for maintenance therapy. Typical dosage range for males is 250-1000 mg per week. Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit. Warming and shaking the vial should redissolve any crystals that may have formed during storage at low temperatures.
